Commentary
For the ओ of a nominal stem + अ of the Accusative case-ending अम् and अस् the single substitute is आ।
The word औतः is a compound of आ + ओतः ॥ Thus गौ - अम्, = गाम्, गो + अस् = गाः ॥ Thus गां पश्य, गाः पश्यः ॥ This debars the Vriddhi of 7.1.90. So also द्यो or द्याः पश्य; as the word द्यो is also a nominal stem ending in ओ ॥ The Sarvanamasthana affixes are णित् after this word also (see 7.1.90) which would have caused Vriddhi, therefore, this आ debars the Vriddhi. The word अम् here means the affix of the Accusative Singular, as it is read in connection with the case-affix शस्, and as the word सुप् of the last sutra governs this also. Therefore अम् the verbal Tense-affix of the Imperfect is not meant: thus we have अचिनवम्, असुनवम् ॥
